[0008] By adopting the above technical solution, when the staff installs the filter cloth on the filter cartridge, the staff needs to put the fixing hoop on the filter cloth. During this process, the staff needs to make the threaded hole and the through hole face each other. At this time, the staff needs to turn the bolt to install the bolt into the threaded hole, so that the bolt and the fixing hoop fix the filter cloth, thereby reducing the probability of the filter cloth and the filter cartridge being separated from each other, thereby improving the stability of the device.

[0009] Furthermore, a plurality of limiting rods are fixedly provided on the side wall of one of the connecting plates, and a plurality of limiting holes are penetrated through the side wall of the other connecting plate, and the limiting rods and the limiting holes match each other.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] like Figure 1-3 As shown, the embodiment of the present application discloses an antistatic filter cartridge, including a filter cartridge 1, a mounting plate 11, a filter cloth 12, a connecting plate 13, a grounding wire 14, a fixing hoop 3, a bolt 31, a limiting rod 4 and a rubber pad 5. The filter cartridge 1 is a tubular structure, and its axis is horizontal. The mounting plate 11 is a rectangular plate-like structure, and the mounting plate 11 is fixedly arranged on the bottom surface of the filter cartridge 1, and a plurality of filter holes 2 are provided in a circular array on the outer wall of the filter cartridge 1. The filter cloth 12 is installed on the outer wall of the filter cartridge 1, and an antistatic material is applied on the outer wall of the filter cloth 12. The cross section of the connecting plate 13 is arc-shaped, and its axis coincides with the axis of the filter cartridge 1. Two connecting plates 13 are provided and fixedly arranged at the two ends of the filter cartridge 1, respectively, and a plurality of connecting holes 21 are provided through the side wall of the connecting plate 13. The grounding wire 14 is provided on one of the connecting plates 13 for grounding.

[0031] When the staff needs to use the filter cartridge 1, the staff needs to connect the other end of the grounding wire 14 to the ground. During the working process, the filter holes 2 on the filter cartridge 1 and the filter cloth 12 filter impurities in the air. In addition, the staff connects the two filter cartridges 1 to each other through the connection holes 21 on the connection plate 13. During the connection process, the staff fixes the two filter cartridges 1 to each other through the screw and the nut. In this process, the outer wall of the filter cloth 12 is coated with antistatic material and grounded with the grounding wire 14, which reduces the probability of the filter cartridge 1 catching fire due to static electricity, thereby reducing safety hazards.

[0032] The upper surface of the mounting plate 11 is provided with a plurality of threaded holes 22, a plurality of fixing hoops 3 are provided and are all installed on the outer wall of the filter cloth 12, and a plurality of through holes 23 are penetrated through the plurality of fixing hoops 3. A plurality of bolts 31 are provided and are respectively installed in the plurality of threaded holes 22, and the bolts 31 penetrate through the through holes 23 and are threadedly connected with the threaded holes 22.

[0033] When the staff installs the filter cloth 12 on the filter cartridge 1, the staff needs to put the fixing hoop 3 on the filter cloth 12. During this process, the staff needs to make the threaded hole 22 face the through hole 23. At this time, the staff needs to rotate the bolt 31, and then install the bolt 31 into the threaded hole 22, so that the bolt 31 and the fixing hoop 3 fix the filter cloth 12, thereby reducing the probability of the filter cloth 12 and the filter cartridge 1 separating from each other, thereby improving the stability of the device.

[0034] The limiting rod 4 is a round rod structure with a horizontal axis. There are multiple limiting rods 4 fixedly arranged on the side wall of one of the connecting plates 13. A plurality of limiting holes 24 are penetrated through the side wall of the other connecting plate 13, and the limiting rods 4 and the limiting holes 24 match each other.

[0035] When the staff needs to connect the two filter cartridges 1 to each other, the staff needs to align the limit rod 4 with the limit hole 24. Then, the staff moves the filter cartridge 1 to slide the limit rod 4 into the limit hole 24. At this time, the connection holes 21 are aligned with the connection holes 21, thereby reducing the difficulty of the staff to align the connection holes 21, thereby reducing the difficulty of the staff's work.

[0036] In order to extend the service life of the device, the fixing hoop 3 is made of stainless steel. Stainless steel has good toughness, and the fixing hoop 3 made of stainless steel reduces the probability of deformation and damage of the fixing hoop 3 when the staff fixes the filter cloth 12, thereby extending the service life of the device.

[0037] The rubber pad 5 is fixedly arranged on the inner ring of the fixing hoop 3 , and the rubber pad 5 is a rubber pad 5 made of silicone rubber.

[0038] Silicone rubber has good elasticity. The rubber pad 5 made of silicone rubber increases the upper limit of the maximum static friction between the fixing hoop 3 and the filter cloth 12, thereby reducing the probability of the filter cloth 12 and the filter cartridge 1 being separated from each other, thereby improving the stability of the device.

[0039] In order to reduce the difficulty of the staff's work, the fixing hoop 3 and the rubber pad 5 are bonded together by glue. The fixing hoop 3 and the rubber pad 5 are bonded together by glue to reduce the probability of the fixing hoop 3 and the rubber pad 5 being separated from each other. In addition, the fixing hoop 3 and the rubber pad 5 are bonded together by glue to reduce the difficulty of the staff to disassemble the fixing hoop 3 and the rubber pad 5, thereby reducing the difficulty of the staff's work.

[0040] In order to reduce the working difficulty of the staff, the mounting plate 11 is a mounting plate 11 made of plastic material. The mounting plate 11 made of plastic material reduces the difficulty of the staff to open the threaded hole 22 on the mounting plate 11, thereby reducing the working difficulty of the staff.

[0041] In order to reduce the difficulty of the work of the staff, a connecting ring 6 is installed at one end of the grounding wire 14 away from the connecting plate 13. The connecting ring 6 reduces the difficulty of the staff to fix the grounding wire 14 to the ground, thereby reducing the difficulty of the staff's work.

[0042] The use principle of an antistatic filter cartridge in this embodiment is as follows: when the staff needs to use the filter cartridge 1, the staff needs to connect the other end of the grounding wire 14 to the ground. During the working process, the filter holes 2 on the filter cartridge 1 and the filter cloth 12 filter impurities in the air. In addition, the staff connects the two filter cartridges 1 to each other through the connection holes 21 on the connecting plate 13. During the connection process, the staff fixes the two filter cartridges 1 to each other through the screw and the nut. During this process, the antistatic material is applied on the outer wall of the filter cloth 12 and the grounding wire 14 is used for grounding, which reduces the probability of the filter cartridge 1 catching fire due to static electricity, thereby reducing safety hazards.

[0043] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
